There are two problems with your findings: 1. MPD does not contain any code which creates SOCK_DGRAM, even less so with AF_UNIX. This is not MPD! 2. Any time MPD exits due to a failure, it will print an error message. This process does not. Again, what you see here is not MPD! 3. Why do you get EPROTONOSUPPORT even though AF_UNIX is allowed? Not a MPD bug, but maybe a systemd bug.
